When Christ who is our life appears, then you also will appear with Him in glory. Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. Because of these things the wrath of God is coming upon the sons of disobedience, in which you yourselves once walked when you lived in them. But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Do not lie to one another, since you have put off the old man with his deeds, and have put on the new man who is renewed in knowledge according to the image of Him who created him, where there is neither Greek nor Jew, circumcised nor uncircumcised, barbarian, Scythian, slave nor free, but Christ is all and in all.
For just as on the racetrack the chariot that takes the lead becomes an obstacle, pressing and checking and preventing the others from stretching out and reaching the goal first, so do the thoughts of the soul and of sin run the race in man. If the thought of sin gets the upper hand from the start, it becomes an obstacle, checking and hindering the soul from approaching God to carry off the victory against sin.
But where God himself truly mounts and guides the soul, he always obtains the victory, skillfully directing and leading with expertise the chariot of the soul to a heavenly mind forever. (Pseudo-Macarius: The Fifty Spiritual Homilies and the Great Letter , pg 42)
